It seems that this Qt version has hardcoded the generic type "Helvetica" as "Sans Serif". Helvetica is defined at /etc/fonts/conf.d/30-metric- aliases.conf as "Nimbus Sans L"
You can change it there or add to your ~/.fonts.conf the following stanzas: <alias binding="same"> <family>Helvetica</family> <accept> <family>Arial</family> </accept> </alias> Then refresh your font cache with fc-cache, restart your application and you should be watching a nice, crisp, hinted font. Substitute Arial for the font of your choice. BEWARE: there are some consequences to this that I don't understand well because of font metrics and what not, read this bug for more information: https://bugs.launchpad.net/ubuntu/+source/fontconfig/+bug/203824 -- fonts in Qt4 look ugly because it uses Nimbus Sans L instead of Deja Vu Sans for Sans-Serif https://bugs.launchpad.net/bugs/209358 You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to qt4-x11 in ubuntu. -- kubuntu-bugs mailing list kubuntu-b...@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
